Edit 2:

This attack is relentless and dynamic. They have found holes in our system and hit us where we never expected. This has forced us to reconfigure our network and site behavior to prevent repeat attacks.

Voat has been put into "lockdown" mode so things like thumbnail generation are disabled.

Edit:

These guys are actually fairly creative. We might have a worthy opponent here. Buckle up Voat.

Voat is at a stage now that the code can somewhat deal with this without capitulating. Usually these attacks only last 10-12 hours, but this current run has been longer in duration than normal so we are now informing the community that we are actually being maliciously targeted.
